Study on preparation technology of compound Geranium granule
Objective To study the preparation technology of compound Geranium.Methods Using the retention rate of gallic acid and total polysaccharide and the reduction rate of extract as indexes,the water extract was refined and the best refining process was obtained.To study the molding process of compound Geranium.Results The purification technology of water extract was to concentrate the water extract at 70℃ under pressure to medicinal materials:the concentration was 1∶1.1,and placed at 4 ℃ for 24 h.The optimal concentration process of water and alcohol extracts was decompression concentration at 70℃(-0.08～0.07Mpa)to the relative densities of 1.15～1.20 and 1.20～1.25,respectively.The drying process is vacuum drying at 70℃.The best forming process is to use 93％ethanol as binder,add fine powder of extract,and separate fine powder of 8％of extract powder to mix and granulate.Conclusion The preparation technology of compound Geranium granule is reasonable and feasible,which can provide basis for the preparation of compound geranium granule.
